Abstract: The invention relates to a crawler track for tracked vehicles, wherein the chain links are provided with articulated eyes facing one another, in which chain bolts connecting the chain links to one another are arranged. At the respective outer contour of the areas of the articulated eyes facing one another, a contour adaptation takes places on at least a partial circumference of the articulated eye, which on at least a partial area has a curvature, which is zero or positive (convex) in the viewing direction from the adjoining articulated eye end face to the center of the articulated eye.

Abstract: A mounting arrangement for a tensioning device with a tensioning unit in a side carrier of a crawler of a tracked undercarriage in a large machine is disclosed. The tensioning unit is arranged in a side carrier compartment in the side carrier of the crawler, wherein a mounting opening is arranged in the side carrier on the outside thereof in an installation area of the tensioning unit for allowing removal of the tensioning unit, when installed, from the side carrier compartment through the mounting opening transversely to a track running direction.
